Modern-day BIOS, the computer code allowing low-level access to your PC’s hardware, is architecturally quite similar to the original BIOS created 25 years ago for the first IBM Personal Computer. But 25 years is a long time in the technology world, and the inadequacies of BIOS are becoming significant enough that it’s time for a replacement. The heir apparent is Unified Extensible Firmware Interface (UEFI). With the exception of a faster boot time, most of the benefits are technical in nature and should be invisible to the standard user. In fact, you may already have a UEFI system and not know it. Another advantage is that system administrators will find it easier to remotely manage large computer networks. I think the real benefit, however, will come in the future when new interfaces (think USB) or hardware types become available and PC designers won’t have to jump through hoops to get them to work.
